    Default Second language shows benifits to aging brain

    My mom's mom is Mexican and has been fluent in English for ... well as long as I've known her (almost 40 years). However I can only remember her speaking in Spanish 3 times. She has had alzheimer's for the past 15 years, she no longer communicates in any way with anyone, and does not recognize anyone. So I'm wondering if you don't use it (the second language) if you lose any benefits from knowing one.

    LEXINGTON, Ky. (Jan. 10, 2013) Older adults who have spoken two languages since childhood are faster than single-language speakers at switching from one task to another, according to a study conducted at the University of Kentucky College of Medicine.

    The study also found that lifelong bilinguals show different patterns of brain activity than their monolingual counterparts when making the switch.

    The research was led by Brian Gold, associate professor of anatomy and neurobiology, who specializes in cognitive neuroscience. The article, "Lifelong Bilingualism Maintains Neural Efficiency for Cognitive Control in Aging," was published in the Jan. 9 issue of The Journal of Neuroscience.

    As people age, cognitive flexibility the ability to adapt to unfamiliar or unexpected circumstances and related "executive" functions decline. Recent studies suggest lifelong bilingualism may reduce this decline a boost that may stem from the experience of constantly switching between languages. However, how brain activity differs between older bilinguals and monolinguals was previously unclear.

    Gold and his colleague used functional magnetic resonance imaging (fMRI) to compare the brain activity of healthy bilingual adults, ages 60-68, with that of healthy monolingual adults in the same age group, as they completed a task that tested their cognitive flexibility.

    The researchers found that both groups performed the task accurately. However, the bilingual group was faster at completing the task, despite expending less energy in the frontal cortex an area known to be involved in task-switching.

    The researchers also measured the brain activity of younger bilingual and monolingual adults while they performed the cognitive flexibility task.

    Overall, the young adults were faster at performing the task. Being bilingual did not affect task performance or brain activity in the young participants. In contrast, older bilinguals performed the task faster than their monolingual peers and expended less energy in the frontal parts of their brain.

    "This suggests that bilingual seniors use their brains more efficiently than monolingual seniors," Gold said. "Together, these results suggest that lifelong bilingualism may exert its strongest benefits on the functioning of frontal brain regions in aging."

    This research was funded by the U.S. National Institutes of Health and the National Science Foundation.

    Welcome to the Alzheimer's Disease Forum. I am sorry about your grandma.

    I do not have any info on your question, but find it interesting. Maybe someone else will know about this.

    meanwhile I hope you . Will stick round and take part in our group. Alzheimer's is a horrible disease and it can be hard for the caregivers as well as all the family.
    Sometimes the best we can do is to say we care.

    Take care and hope to see more of you. ((((hugs)))) Jo

    Hi Jo6

    Yes Alzheimer's is a pretty crappy disease. But I take a lot of comfort in knowing she's otherwise quite healthy for now

    Alzheimer's disease is a brain disease that can be cured due to some maintenance of rules. The patient face the problems of talking and for this reason practicing language with the other people help them for curing.
